The statements that describes accurately about elements are :
Elements are made up of only one type of atom.
Each element has a unique chemical symbol.
Elements can be identified by their àtomic number
<u>Explanation:</u>
Simple and complete chemical substances are called elements. An element contains only one type of atom. In a periodic table each of the the element occupies unique entry respectively. The atom that is present in an element contains similar number of protons and this is said to be an atomic number. Each element is represented by an unique one or two letters in the periodic table.
One Element differs for another element by the number of protons present in the nucleus. If there is one proton in an atom it is said to be hydrogen atom and if it has two atoms then it is known to be a helium atom.Lithium refers to the atom with three protons.
Answer:
angular velocity
Explanation:
In physics the quantity represented by is the <u>angular velocity, </u>the units of the angular velocity are radians/second.
This is a quantity that represents the speed when the movement of an object follows a circular path.
Mathematically defined as follows:
Where is the period, the time it takes to complete a lap.
<span>Having a wide knowledge of the nervous system and the of how the brain’s different parts collaborate to organize all our movements, senses thoughts, and emotions enable the medical assistants to handle the cognitive and behavioral complications in the patient. It helps them to deal with wounds and falls since the nervous disorder generally affects cognition and movement. Having a wide knowledge of how the nerve impulses are transmitted from the nervous system to the brain, when it is then converted into feelings such as pleasure, pain, cold or hot, the medical assistant will be able to take response immediately on the patient prior they start complaining of sensory indications, such as discomfort, irritating, and unresponsiveness.</span>
Yes it can.

Explanation:
Given that,
Mass of the block, m = 5 kg
Spring constant, k = 2000 N/m
The block is pulled down 5.0 cm from the equilibrium position and given an initial velocity of 1.0 m/s back towards equilibrium.
(a) The angular frequency is given by :
Since, , f is frequency
(b) The velocity of particle executing SHM is given by :
x is displacement from equilibrium position
(c) The total mechanical energy of the motion in SHM is given by :
Hence, this is the required solution.
